LIGAND-FREE STRUCTURE OF STEROL 14ALPHA-DEMETHYLASE FROM MYCOBACTERIUM TUBERCULOSIS IN P2(1) SPACE GROUP
Overview
Sterol 14alpha-demethylase (CYP51), a major checkpoint in membrane sterol, biosynthesis, is a key target for fungal antibiotic therapy. We sought, small organic molecules for lead candidate CYP51 inhibitors. The changes, in CYP51 spectral properties following ligand binding make it a convenient, target for high throughput screening (HTS) technologies. These changes are, characteristic of either substrate binding (type I) or inhibitor binding, (type II) in the active site. We screened a library of 20,000 organic, molecules against Mycobacterium tuberculosis CYP51 (MtCYP51) and examined, the top type I and type II binding hits for their inhibitory effects, against M. tuberculosis in broth culture and spectrally for their ability, to discriminate between MtCYP51 and two reference M. ...
